installer: prefer nix from default profile

Browse source 
Using a nix 2.1 nix-channel/nix-env with a 2.0 nix-daemon doesn't work
because the buildenv implementation was moved to the daemon.  This means
the nix version of the target darwin system can't be used because the
daemon isn't upgraded yet.

    error: unsupported builtin function 'buildenv'
